Alleged shooter Dylann Roof reportedly made racist statements before killing the parishioners. Before the shooting, Roof also posed for pictures with Confederate flags and other racially charged paraphernalia on his website.

The shooting has sparked a national debate about the placement of symbols honoring the Confederacy on public grounds.

Pressure is building in the state to remove the statues at UT-Austin. A Change.org petition has garnered thousands of signatures, and on Tuesday, Rep. Joaquin Castro (D-Texas) called on Texas Governor Greg Abbott (R) and Texas Land Commissioner George P. Bush to take the statues down.

A UT-Austin spokesperson told Business Insider that the graffiti was quickly removed.

This isn't the first time that the statues have been vandalized. According to the UT-Austin spokesperson, there have been at least three instances of vandalism on the Jefferson Davis statue in the past several years. As the Texas Tribune notes, in April someone tagged "Davis Must Fall" on the statue.
